INTRODUCTION

1.1 Project Background

1.1.1 Fortune Pacific Investment Limited (“the Project Proponent”) has proposed to redevelop the

site at Nos. 15-15A, 17, 19, 23 Saigon Street, Yau Ma Tei (“the Site”) as a residential building

with shop/eating on ground floor (“the Project”). The location plan of the Site is shown in

Figure 1-1.

1.1.2 The Site falls within an area zoned “Commercial” (“C”) on the Draft Yau Ma Tei Outline

Zoning Plan No. S/K2/23 (“Draft OZP”). According to the Statutory Notes of the Draft OZP,

the “C” zone is intended “primarily for commercial developments, which may include shop,

services, place of entertainment and eating place, functioning mainly as local shopping centres

serving the immediate neighbourhood.” The proposed “Shop and Services”/”Eating Place”

uses are column 1 uses which are always permitted; whereas provision for “Flat” use is

included under column 2 of the Statutory Notes of the “C” zone which requires planning

permission from the Town Planning Board (TPB) upon application.

1.1.3 Cinotech Consultants Limited has been commissioned by the Project Proponent to prepare an

environment assessment (EA) report in support of the application for permission under

Section 16 of TPB (“the Application”).

1.2 Description of the Existing Site & its Environs

1.2.1 The Site is located at the junction of Saigon Street / Cho Wo Street, Yau Ma Tei with a site

area of about 778 m2. The Site location is illustrated in Figure 1-1.

1.2.2 The Site is currently occupied by 2 tenement buildings located at 15-15A and 17-19 Saigon

Street, and a hotel, namely Travelodge Kowloon, at 23 Saigon Street.

1.2.3 The Site is surrounded mainly by commercial / tenement buildings to its west on the southerly

side of the Saigon Street, and to its south on the northerly side of the Cheong Lok Street that

is separated from the Site by a service lane. While the northerly side of Saigon Street to the

north of the Site is occupied by Novotel Hotel / commercial buildings, and the easterly side

of Chi Wo Street to the east of the Site is occupied by the Diocesan Girls' School.

1.3 Proposed Development

1.3.1 The proposed development comprises one single building block with a total of 26 storeys

(including G/F) and a basement floor (“the Proposed Development”). The first 3 floors,

namely the G/F, 1/F and 2/F, shall be used for shops and services /eating place, plant rooms

and covered landscape & play area respectively. While the upper floors, namely 3/F to 25/F

shall be used for residential purpose. The basement floor will be used for an underground

carpark with about 24 spaces. The notional building plan of the Proposed Development is

shown in Appendix 1-1.

1.4 Scope of Study

1.4.1 This EA is prepared to assess the potential environmental impact/benefit associated with the

implementation of the Project in support of the submission of the Application. The assessment

has been undertaken with reference to the guidance for environmental considerations provided

in Chapter 9 “Environment” of the Hong Kong Planning Standards and Guidelines (HKPSG).






1.4.2 The key environmental issues with potential environmental impacts arising from the Project

are identified, based on the environment of the Project, as air quality, noise and sewerage.

1.4.3 The assessment has covered the following major aspects;

Air quality Impact

Noise Impact

1.4.4 The Sewerage Impact Assessment (SIA) is provided in a separate report under the

Application.






AIR QUALITY IMPACT

2.1 Introduction

2.1.1 This chapter identifies and evaluates potential air quality impact due to the Project, and

recommends appropriate mitigation measures for the potential impact.

2.2 Legislations, Standards and Guidelines

2.2.1 The air quality impact assessment was carried out with reference to the Hong Kong Planning

Standards and Guidelines (HKPSG). The minimum buffer distance from the emission sources

(i.e. Roads and Highways, and Industrial Area) are recommended in the Hong Kong Planning

Standards and Guidelines (HKPSG) and are summarized in Table 2-1.

>40m >10m Active and passive recreation uses

Note:

(i) In situations where the height of chimneys is not known, use the set of guidelines marked with

an asterisk for preliminary planning purpose and refine as and when more information is

available.

(ii) The buffer distance is the horizontal, shortest distance from the boundary of the industrial lot,

the position of existing chimneys or the edge of road kerb, to the boundary of open space sites.

(iii) The guidelines are generally applicable to major industrial areas but NOT individual large

industrial establishments which are likely to be significant air pollution sources. Consult EPD

when planning open space sites close to such establishments.

2.2.2 The Control of Air Pollution in Car Parks (ProPECC PN 2/96) provides guidance on the






control of air pollution in car parks including air quality guidelines required for the protection

of public health; and factors that should be considered in the design and operation of car parks

in order to achieve the required air quality.

2.3 Study Area & Air Sensitive Receivers

2.3.1 The Study Area for this air quality impact assessment covers the area within 500 m from the

Project boundary. Identified representative air quality sensitive receivers (ASRs) include

existing and planned residential buildings, hospitals and schools in the vicinity of the Project

Site.

2.4 Impact Identification & Evaluation

2.4.1 As the Proposed Development shall be used primarily for residential purposes, the Site per se

is not considered as a major air pollution source during its operation and no major air quality

impact from the Project on nearby sensitive uses during operational phase is expected.

Nevertheless, the exhaust air from the proposed indoor car park in the Project is considered

as a potential source of impact. The proposed carpark should be located and built in

accordance to the requirements stipulated in ProPECC PN2/96 for the design, maintenance

and operation of the ventilation systems to ensure the compliance of the air quality inside car

parks with the concentration limits. The exhaust air should be discharged to the atmosphere

in such a manner and at such a location as not to cause a nuisance to occupants in the building

or of neighbouring buildings, or to the public. Hence, no insurmountable impact on the nearby

sensitive receivers is expected. The impact from nearby emission sources on the project is

assessed in the following sections.

2.4.2 The residential floors in the Proposed Development that rely on openable windows for

ventilation, while the remaining area of the Proposed Development will be ventilated with

multi-split air-conditioning or VRF system. The fresh air intake for air sensitive uses of this

Project will have sufficient buffer distance of 5m from nearby emission sources.

2.4.3 The Site is bounded by Saigon Street, and Chi Wo Street located immediately to the north,

east of the Site respectively. With reference to The Annual Traffic Census - 2019, Saigon

Street belongs to the Local Distributor, and the rest of the roads are also considered to be local

distributors according to the Traffic Consultant. Therefore, the fresh-air intake locations in the

Proposed Development should be kept from the kerbs of both road sections by a buffer

distance of 5m, according to Table 2-1. The area within the adopted buffer distance for the

Site is indicated in Figure 2-1.

2.4.4 No industrial chimney was identified within 200m from the Site.

2.5 Mitigation Measures

2.5.1 All fresh air intake required by the air conditioning or mechanical ventilation for the Proposed

Development should be located at a minimum of the buffer distance to minimize traffic

emission impact on the quality of the air intake. The car park should be designed according

to the requirements in ProPECC PN 2/96.

2.6 Conclusion

2.6.1 Representative air quality sensitive receivers in the Study Area have been identified. The

Proposed Development at the Site per se is not considered as a major air pollution source






during its operation and air quality impact from the Project on nearby sensitive uses during

operational phase is not expected. As the premise itself is an ASR, the emission source within

500m of the site has been assessed, no industrial chimney was identified within 200m from

the proposed development site boundary. The minimum buffer distance from the premise to

the nearby roads, as recommended in HKPSG, should be adopted.






NOISE IMPACT

3.1 Introduction

3.1.1 This chapter identifies and evaluates potential noise impact due to the Project, and

recommends appropriate mitigation measures for the potential impact.

3.2 Legislations, Standards and Guidelines

Road Traffic Noise

3.2.1 HKPSG provides guidance on acceptable road traffic noise levels at the openable windows of

various types of noise sensitive buildings. The relevant criteria are shown in Table 3-1.

Table 3-1 HKPSG Road Traffic Noise Planning Criteria

Uses Road Traffic Noise

L10, (1hr) dB(A)

Domestic Premises 70

Hotel and Hostels 70

Offices 70

Educational institutions 65

Hospital & Clinics 55

Places of public worship and courts of law 65

Note: The above criteria apply to noise sensitive uses which rely on opened window for ventilation.

Existing & Planned Fixed Noise

3.2.2 Fixed noise sources, such as the public address system, building services system, ventilation

system, and the operation of the Project is controlled under the NCO and “Technical

Memorandum for the Assessment of Noise from Places Other Than Domestic Premises,

Public Places or Construction Sites” (IND-TM). According to the IND-TM, the Acceptable

Noise Level (ANL) for a Noise Sensitive Receiver (NSR) is determined by the Area Sensitive

Ratings (ASR); which classify a NSR based on the type of the area within which the NSR is

located, the time of day under consideration, and the degree of the effect on the NSR of

particular Influencing Factors (IFs). The different types of area containing the NSR are

categorised into the rural area, low density residential area, urban area and other areas, with

reference to Table 1 of the IND-TM. While the IFs, defined as industrial areas or area

containing a number of factorises or major road with an annual average daily traffic flow

(AADT) in excess of 30,000, should be assessed for their influence on the NSR according to

the degree of influence (“not affected”, “indirectly affected” and “directly affected”).

3.2.3 The HKPSG states that all planned fixed noise sources should be located and designed so that

when assessed in accordance with the IND-TM, the level of the intruding noise at the facade

of the nearest sensitive use should be at least 5 dB(A) below the appropriate ANL shown in

Table 2 of the IND-TM or the background noise level, whichever is lower. When the

prevailing background noise levels would be adopted as the assessment criteria, the prevailing

background noise levels, L90(1-hour), at the relevant NSRs shall be measured during the typical

operation hours of the fixed plant within daytime, evening and night times. The Acceptable

Noise Levels (ANLs) assigned to for different Area Sensitivity Ratings (ASRs) are given in

Table 3-2.

3.3 Noise Sensitive Receivers

Road Traffic Noise

3.3.1 In order to evaluate the noise impacts from the Project, representative noise sensitive receivers

(NSRs), which rely on opened windows for ventilation, within 300m from the boundary of

the Project site are identified. The noise assessment points were located 1.2m above the slab

level and 1m away from the façade. All potential window and balcony locations at all

residential flats are covered. Their locations of the noise assessment points for the Traffic

Noise Assessment are listed in Table 3-3 and illustrated in Figure 3-2.

3.3.2 The Site is located in Yau Ma Tei where it is dominated by commercial activities, which is

characterised as “Urban Area” with reference to the definition of the type of area containing

the NSR as described in the IDM-TM. Although no industrial activities were found in the

environs, noisy fixed plants in the ventilation system at the commercial buildings were

considered as potential operational fixed plant noise source affecting the NSRs at the Proposed

Development. Their locations of the representative NSRs adopted for noise assessment points

are listed in Table 3-4 and illustrated in Figure 3-2 for Fixed Plant Noise Assessment.

3.3.3 Major roads, namely Nathan Road, Jordan Road and Gascoigne Road to the west, south and

east of the Site respectively are identified as potential IFs. According to TD’s updated Annual

Traffic Census (ATC2020), the concerned roads have an AADT of more than 30,000. The Site

is directly affected by the IFs as the NSRs are expected to have direct line of sight to the

concerned roads, with reference to the façade orientation of layout of the Site. Hence, the ASR

of the Site and the neighbourhood would be classified as “C”. Correspondingly, the criteria






for existing noise source would be 70 dB(A) for day and evening time and 60 dB(A) for night

time as tabulated in Table 3-2.

3.4 Assessment Methodology

Traffic Road Noise

3.4.1 An in-house noise model (MARC) was used to predict the traffic noise levels arising from the

road network. It adopts the methodology provided in the UK Department of Transport’s

Calculation of Road Traffic Noise (CRTN) 1988, which is stipulated in Chapter 9, Section

4.2.7 of the HKPSG for assessing road traffic noise impact. Road traffic noise levels are

presented in terms of noise levels exceeded for 10% of the one-hour period for the hour having

the peak traffic flow [L10 (1-hour) dB(A)].

3.4.2 The assessment was based on the projected peak hour flows for the worst year within 15 years

after completion of the Project in Year 2027. Based on the traffic forecast provided by the

traffic consultant, the AM/PM peak hour flows in Year 2042 will be the maximum projected

peak hour traffic flow within 15 years from the completion of the Project. The major roads

within 300m from the boundary of the Project have been included in the assessment and are

shown in Appendix 3-1.

3.4.3 Two scenarios have been considered in the traffic noise impact assessment. The first one is a

base scenario of the proposed layout without any mitigation measures. The second scenario

is a mitigated scenario with incorporation of mitigation measures in the Proposed

Development, such as acoustic windows, etc on top of the base scenario at NSR with

exceedance recorded.


3.4.4 The fixed plant noise impact on the sensitive use at the Proposed Development was quantified

by the predicted fixed noise level (sound pressure level) at the assessment points at the

adopted assessment points. The calculations were made based on the following standard

formula:

SPL = SWL – DC – FC – SC –TC

where

SPL Sound Pressure Levels at receiver, in dB(A)

SWL Sound Power Levels of Fixed Noise Sources, in dB(A)

DC Distance Correction, in dB by DC = 20×log10 (D) + 8, D is the slant distance between the NSR and noise






source location in metres

FC Façade Correction of 3 dB

SC Screening Correction of 10dB reduction when direct line of sight is blocked by barrier 1

TC Tonality/Impulsiveness/Intermittency Correction of 3dB(A) is assumed

3.4.5 As the existing fixed plants in the surrounding buildings cannot be easily accessed for the

identification of their model and the respective noise levels. The sound power levels of the

major fixed plants contributing to the sound pressure level at the assessment points were

adopted with reference to the make of the plants and assumed ventilation system for the

building such as central ventilation with water cooling or air-cooled or multi-split air

conditioning system. Planned fixed plants have also been assessed for their impact on the

Project.

3.4.6 The Proposed Development shall be used primarily for residential purposes with some

commercial activities. The dwellings would reply on opened windows and single split air

conditioning units while the commercial areas would use multi split air-conditioning for

ventilation. As the power required for those units are expected to be small, the planned fixed

plant noise impact arising from the Project is expected to be negligible. Nevertheless, the

planned fixed plant at the Proposed Development should be designed with reference to the

standard stipulated in the HKPSG, as described in Section 3.2.

3.5 Impact Identification & Evaluation

Traffic Flow Data and Assessment Year

3.5.1 According to the prediction by the traffic consultant, the maximum traffic projections within

15 years upon occupation of the proposed development, that is between Year 2027 (year of

population intake) and Year 2042 would occur in AM Peak hour of Year 2042. Therefore, the

predicted traffic flows during Peak hour (AM) of Year 2042 were adopted for road traffic

model.

Predicted Traffic Noise Impact in Base Scenario

3.5.2 The summaries of predicted traffic noise level are listed in Table 3-5 &Table 3-6. The detailed

results of the Base Scenario are listed in Appendix 3-2.

3.5.3 The predicted traffic noise levels show that the proposed development suffered from the traffic

noise impact, especially facing Saigon Street. The highest traffic noise level is found to be

72.9 dB(A), at Flat J (24/F, 25/F), which exceeds the 70 dB(A) criteria by around 3 dB(A).

3.5.4 The noise exceedance has been found in the residential flats that directly facing Saigon Street,

i.e. Flats D, E, F, G, H & J, at Living Room (Balcony) and Bedroom. Only the flat with

window for ventilation facing Saigon Street exceeded the criteria of 70dB(A). The compliance

rate of residential flats is (174/230 =) 76%. The highest exceedance is 3 dB(A).

1 The screening correction is adopted with reference to the Technical Memorandum on Noise from Construction Work Other

than Percussive Pilling (TM1)

Predicted Traffic Noise Impact in Mitigation Scenario

3.5.5 Acoustic windows and acoustic balcony shall be adopted to provide at-receiver mitigation

measures to further minimize the traffic noise impact on the proposed development. Subject

to detailed design, the following mitigation measures are proposed in this mitigated scenario:

i. Top-hung Acoustic Windows2 (Noise Reduction: 5 dB(A))

The design of a top-hung window with a horizontal fin on the bottom of the window

coupled with Micro-perforated absorbers (MPA) on the inner side of the window and

a pelmet in the indoor area behind the top-hung window, can effectively resist noise

from entering domestic premises directly and hence minimize the impact on the

residents. The design is similar to the type adopted in Hong Tsuen Road Residential

Development at Sai Kung (Park Mediterranean). The ratio of vertical distance from

opening of the top-hung window to the length of the horizontal acoustic fin (aspect

ratio) will be less than the aspect ratio (0.55) of the acoustic window in Park

Mediterranean. Section drawings of the typical Acoustic Windows are illustrated in

Figures 3-5. For assessment purpose, a 5 dB reduction has been adopted in the

calculation. A sample section drawing extracted from the sale brochure of Park

Mediterranean is provided in Figure 3-6 for reference.

ii. Acoustic Balcony Door3 (Noise Reduction: 2-3 dB(A))

This type of acoustic balcony door works similar to the acoustic window (baffle type).

The air gap width (100mm-175mm) and overlapping distance (100mm+) of the doors

will also strictly follow the guidance for acoustic windows (baffle type) in PNAP APP-

130 to achieve both ventilation and acoustic performances.

3.5.6 Top-hung Type Acoustic Window has been proposed in the current assessment as it has been

adopted and well proven in private housing for years. Therefore, the calculated traffic noise

level is reliable and conservative. Both mitigation measures, Top-hung Type Acoustic

Window and Acoustic Balcony Door will be adopted for bedroom and Balcony (Living room)

respectively.

3.5.7 The design of a top-hung type acoustic window with a horizontal fin on the bottom of the

window coupled with Micro-perforated absorbers (MPA) on the inner side of the window and

a pelmet in the indoor area behind the top-hung window. The ratio of vertical distance from

opening of the top-hung window to the length of the horizontal acoustic fin (aspect ratio)

should be adopted with reference to the required noise reduction level.

3.5.8 The required specifications for the design of Baffle Type Acoustic Windows/Door,

specifically on whether any combination of window pane separation, windows height,

window opening and windows overlapping, etc. would be explored in the next detailed design

stage to achieve noise compliance at all NSRs with the performance of the proposed

mitigation measures being optimised.

3.5.9 Mitigation measures have been proposed to all locations with traffic noise exceedance. The

locations of the proposed mitigation measures are illustrated in Figures 3-3 and listed in

Appendix 3-3.

3.5.10 Mitigation measures have been proposed as far as practicable based on the current design.

The use of at-receiver mitigation measures with higher acoustic performance is only possible

in detail design stage where the actual dimensions of the rooms are known. Also, considering

the max traffic noise exceedance is 3 dB(A) in the base scenario, 100% compliance rate is

archivable with careful design and selection of suitable mitigation measure.

Existing & Planned Fixed Noise Source

3.5.11 The Proposed Development is surrounded by school, commercial buildings, residential

buildings and Hotel, from which water-cooling towers, air-cooled chillers in VRV/VRF units

were identified as fixed noise source. When compared with the water cooling towers, the noise

attributed to the small chiller units and VRV/VFR units are much less significant. In addition,

for chillers and VRV/VRF units located at 90 and above have high attenuation of 47dB(A)

which would ensure the compliance of the 50dB(A) limit for night time, assuming that the

plants are operated 24 hours. Hence, the small chillers and VRV/VRF units located outside

this separation distance such as those from Manulife Provident Funds Place (to the west of

the Site) and Hang Shing Building (west), Crason Commercial Building (west) and Hotel

Stage (north), Noble Park Hotel (north) are omitted from the calculations of predicted fixed

noise level at the assessment points. Chillers and VRV/VRF units located within 90m were

found at Diocesan Girls' School Place 18, ACME building and Largos Hotel. Since the plants

in the school are blocked by a fence wall in the School while the ACME building and Largos

Hotel are completely blocked by the buildings on Cheong Lok Street, no significant noise

level is anticipated from the noise sources and therefore are omitted from the calculations.

3.5.12 As the site at Novotel Hong Kong Nathan Road Kowloon is expected to be redeveloped into

a residential-cum-commercial complex prior to the commencement of the Project, with

reference to the planning application A/K2/218. The fixed plant noise from hotel has been

omitted and as no major noise source is expected from the redevelopment which is dominated

by residential uses with fixed plant designed to HKPSG standard. The fixed noise source from

the site at Novotel Hong Kong Nathan Road Kowloon was not considered in the calculations.

3.5.13 Hence, all water cooling towers in the vicinity of the Site and VRV/chillers at Place 18 are

adopted for calculating the predicted noise levels at the assessment points. The Potential noise

sources assessed in the calculations are listed in Table 3-8, and illustrated in Figures 3-4 to

3-5.

3.5.14 The Sound Power Level (SWL) of the concerned chillers/water cooling towers are adopted

with reference to those available in the market with similar make and capacity. According to

the fixed plant noise assessment, no exceedance of the adopted noise standards at the assessed

NSRs is anticipated. The summary of predicted noise level are summarised in Table 3-9 and

detailed in Appendix 3-4.

3.6 Conclusion

3.6.1 During the operation of the Project, potential noise impact from traffic and fixed plant noise

have been assessed. Traffic noise impact has been taken into consideration in the base scenario

to minimise noise impact especially for openable windows facing Saigon Street. In base

scenario, the result shows that 75.7% of flats complies with the 70 dB(A) traffic noise

assessment criteria as demonstrated, with maximum residual noise exceedance up to around

3dB. In the mitigated scenario, at-receiver mitigation measures are also adopted to improve

the noise compliance. Two types of mitigation measures (Type I: Acoustic Window (Top-

hung Windows); Type II: Acoustic Balcony) are adopted simultaneously, the compliance rate

has been largely increased to 100% which fulfilling the traffic noise criteria for Domestic

Premises of 70 dB(A). Therefore, no adverse impact from traffic noise is anticipated.

3.6.2 Noisy fixed plants of major concern were identified as the chillers and water-cooling tower

from the ventilation systems in the surroundings during daytime, evening and night-time.

According to the fixed plant noise assessment, no exceedance of the adopted noise standards

at the representative NSRs is anticipated. The fixed plant noise assessment should be reviewed

during the detailed design stage to ensure compliance with the standard stipulated in the

HKPSG






CONCLUSION

4.1.1 Fortune Pacific Investment Limited has proposed to redevelop the area at 15-15A, 17, 19, 23

Saigon Street, Yau Ma Tei as a residential building with shop/eating on ground floor. Cinotech

Consultants Limited has been commissioned by the Project Proponent to prepare an

environment assessment report in support of the application for permission under Section 16

of TPB.

4.1.2 This EA is prepared to assess the potential environmental impact/benefit associated with the

implementation of the Project in support of the submission of the Application. The assessment

has been undertaken with reference to the guidance for environmental considerations provided

in Chapter 9 “Environment” of the Hong Kong Planning Standards and Guidelines.

4.1.3 The key environmental issues with potential environmental impacts arising from the Project

are identified, based on the environment of the Project, as air quality, noise and sewerage. The

Sewerage Impact Assessment is provided in a separate report under the Application.

Air

4.1.4 During operation phase, the proposed development at the Site itself is not considered as a

major air pollution source during its operation, despite the presence of the proposed indoor

car park. Since the proposed carpark will be designed and built in accordance to the

requirements stipulated in ProPECC PN2/96, no major air quality impact from the Project on

nearby sensitive uses during operational phase is expected. As the premise itself is an ASR,

the emission source within 500m of the site has been assessed and only traffic emission is

identified. The minimum buffer distance from the fresh air intakes to the nearby roads, as

recommended in HKPSG, should be adopted.

Noise

4.1.5 During the operational phase of the Project, potential noise impact from traffic and fixed plant

noise have been assessed. Traffic noise impact has been taken into consideration in the base

scenario to minimise noise impact especially for openable windows facing Saigon Street. In

base scenario, the result shows that 75.7% of flats complies with the 70 dB(A) traffic noise

assessment criteria as demonstrated, with maximum residual noise exceedance up to around

3dB. In the mitigated scenario, at-receiver mitigation measures are also adopted to improve

the noise compliance. Two types of mitigation measures (Type I: Acoustic Window (Top-

hung Windows); Type II: Acoustic Balcony) are adopted simultaneously, the compliance rate

has been largely increased to 100% which fulfilling the traffic noise criteria for Domestic

Premises of 70 dB(A). Therefore, no adverse impact from traffic noise is anticipated.

4.1.6 Noisy fixed plants of major concern were identified as the chillers and water-cooling tower

from the ventilation systems in the surroundings during daytime, evening and night-time.

According to the fixed plant noise assessment, no exceedance of the adopted noise standards

at the representative NSRs is anticipated. The fixed plant noise assessment should be reviewed

during the detailed design stage to ensure compliance with the standard stipulated in the

HKPSG
